NMR and EPR studies of membrane transporters.
In order to fulfill their function, membrane transport proteins have to cycle through a number of conformational and/or energetic states. Thus, understanding the role of conformational dynamics seems to be the key for elucidation of the functional mechanism of these proteins. However, membrane proteins in general are often difficult to express heterologously and in sufficient amounts for struct...
متن کاملNMR Studies of Membrane Structure and Dynamics
Over the past decade, there has been considerable interest in the motional state of the phospholipid bilayer membrane. The motivation underlying these efforts has been the contention that the phospholipid bilayer is the basic matrix in which membrane proteins are embedded to form the biological membrane, and that the permeability and mechanical properties of the membrane, as well as the enzymat...
متن کاملApplication of Solution NMR to Structural Studies on α-Helical Integral Membrane Proteins.
A large portion of proteins in living organisms are membrane proteins which play critical roles in the biology of the cell, from maintenance of the biological membrane integrity to communication of cells with their surroundings. To understand their mechanism of action, structural information is essential. Nevertheless, structure determination of transmembrane proteins is still a challenging are...
متن کاملSolution NMR studies on the orientation of membrane-bound peptides and proteins by paramagnetic probes.
Many peptides and proteins are attached to or immersed in a biological membrane. In order to understand their function not only the structure but also their topology in the membrane is important. Solution NMR spectroscopy is one of the most often used approaches to determine the orientation and localization of membrane-bound peptides and proteins. Here we give an application-oriented overview o...
متن کاملReverse micelle encapsulation of membrane-anchored proteins for solution NMR studies.
Perhaps 5%-10% of proteins bind to membranes via a covalently attached lipid. Posttranslational attachment of fatty acids such as myristate occurs on a variety of viral and cellular proteins. High-resolution information about the nature of lipidated proteins is remarkably sparse, often because of solubility problems caused by the exposed fatty acids. Reverse micelle encapsulation is used here t...
